METHODS: This observational study was conducted between December 2018 and October 2019 at 25 PHCs in three regions in Malaysia. Each PHC was linked to one or more hospitals, for referral of seropositive participants for confirmatory testing and pretreatment evaluation. Treatment was provided in PHCs for non-cirrhotic patients and at hospitals for cirrhotic patients.
RESULTS: During the study period, a total of 15 366 adults were screened at the 25 PHCs, using RDTs for HCV antibodies. Of the 2020 (13.2%) HCV antibody-positive participants, 1481/2020 (73.3%) had a confirmatory viral load test, 1241/1481 (83.8%) were HCV RNA-positive, 991/1241 (79.9%) completed pretreatment assessment, 632/991 (63.8%) initiated treatment, 518/632 (82.0%) completed treatment, 352/518 (68.0%) were eligible for a sustained virological response (SVR) cure assessment, 209/352 (59.4%) had an SVR cure assessment, and SVR was achieved in 202/209 (96.7%) patients. A significantly higher proportion of patients referred to PHCs initiated treatment compared with those who had treatment initiated at hospitals (71.0% vs 48.8%, p<0.001).
CONCLUSIONS: This study demonstrated the effectiveness and feasibility of a simplified decentralised HCV testing and treatment model in primary healthcare settings, targeting high-risk groups in Malaysia. There were good outcomes across most steps of the cascade of care when treatment was provided at PHCs compared with hospitals.
METHODS: The programme was developed as a student-centred, collaborative approach to achieve the learning outcomes for dental and chiropractic students. Second-year dental students (n = 46) and chiropractic students (n = 23) in their fourth year participated in the programme. The focus of the programme was to address the prevention of work-related musculoskeletal disorders (WMSDs) amongst dental students and to provide the chiropractic students with the opportunity to assess and identify risk factors for WMSDs in the dental setting. The readiness for interprofessional learning scale (RIPLS) questionnaire was completed prior to the interprofessional education programme and once again afterwards to determine dental and chiropractic students' awareness of roles and responsibilities of the other profession, and their attitudes to interprofessional education and teamwork.
RESULTS: Dental and chiropractic students showed similar levels of readiness for shared learning. The results of this study suggest that the IPL programme contributed to the development of the students' positive perceptions towards the positive professional identity and the roles of other healthcare professionals.
CONCLUSION: This study provides initial support for the integrated interprofessional learning experiences within the school. The results of the study will shape future curricula changes to further strengthen interprofessional education and subsequent interprofessional collaborative care.
MATERIALS AND METHODS: To examine this hypothesis, in the present study, the associations between CYP3A5 variants (rs776746 and rs1419745) and response to carbamazepine and valproic acid monotherapy in Malaysian epileptic patients were evaluated.
RESULTS: A total of 288 Malaysian epileptic patients were recruited and further reviewed, of whom 63 patients were on carbamazepine monotherapy, and 85 patients were on valproic acid monotherapy. There was no patient with drug hypersensitivity syndrome within the population. Subjects were genotyped by using Sequenom MassARRAY platform. This study found a significant association of CYP3A5 rs776746 with the carbamazepine treatment response in total patients (p = 0.026) and Malay ethnic subgroup (p = 0.006). In addition, a marginal significant association of CYP3A5 rs1419745 with carbamazepine treatment response was reported in the Malays. Similarly, CYP3A5 rs776746 was associated with valproic acid response in total patients (p = 0.037) and Malays (marginal p = 0.05).
CONCLUSION: Our findings suggest that CYP3A5 polymorphisms affect carbamazepine and valproic acid response in Malaysian epileptic patients.
Methods: A total of 174 samples of seven cephalopod species were collected from the west coast of Peninsular Malaysia. Both upper and lower beaks were extracted from the samples and the left lateral views of upper and lower beak images were acquired. Three types of traditional morphometric features were extracted namely grey histogram of oriented gradient (HOG), colour HOG, and morphological shape descriptor (MSD). In addition, deep features were extracted by using three pre-trained convolutional neural networks (CNN) models which are VGG19, InceptionV3, and Resnet50. Eight machine learning approaches were used in the classification step and compared for model performance.
Results: The results showed that the Artificial Neural Network (ANN) model achieved the best testing accuracy of 91.14%, using the deep features extracted from the VGG19 model from lower beak images. The results indicated that the deep features were more accurate than the traditional features in highlighting morphometric differences from the beak images of cephalopod species. In addition, the use of lower beaks of cephalopod species provided better results compared to the upper beaks, suggesting that the lower beaks possess more significant morphological differences between the studied cephalopod species. Future works should include more cephalopod species and sample size to enhance the identification accuracy and comprehensiveness of the developed model.
RESULTS: At present, the classifier used has achieved an accuracy of 100% based on skulls' views. Classification and identification to regions and sexes have also attained 72.5%, 87.5% and 80.0% of accuracy for dorsal, lateral, and jaw views, respectively. This results show that the shape characteristic features used are substantial because they can differentiate the specimens based on regions and sexes up to the accuracy of 80% and above. Finally, an application was developed and can be used for the scientific community.
CONCLUSIONS: This automated system demonstrates the practicability of using computer-assisted systems in providing interesting alternative approach for quick and easy identification of unknown species.
MATERIALS AND METHODS: Sound extracted human molars were randomly divided into: manufacturer's instructions (MI), manual blend 2 mm (MB2), and manual blend 4 mm (MB4). Occlusal enamel was removed and flattened, dentin surfaces were bonded by Prime & Bond universal (Dentsply and Optibond FL, Kerr). For the MI group, adhesives were applied following the manufacturer's instructions then light-cured. For MB groups, SDR flow+ bulk-fill flowable composite resin was applied in 2- or 4-mm increment then manually rubbed by a micro brush for 15 s with uncured dentine bonding agents and the mixture was light-cured. Composite buildup was fabricated incrementally using Ceram.X One, Dentsply nanohybrid composite resin restorative material. After 24-h water storage, the teeth were sectioned to obtain beams of about 0.8 mm2 for 24-h and thermocycled micro-tensile bond strength at 0.5 mm/min crosshead speed. Degree of conversion was evaluated with micro-Raman spectroscopy. Contraction gaps at 24 h after polymerization were evaluated and atomic force microscopy (AFM) nano-indentation processes were undertaken for measuring the hardness across the interface. Depth of resin penetration was studied using a scanning electron microscope (SEM). Bond strength data was expressed using two-way ANOVA followed by Tukey's test. Nanoindentation hardness was separately analyzed using one-way ANOVA.
RESULTS: Factors "storage F = 6.3" and "application F = 30.11" significantly affected the bond strength to dentine. For Optibond FL, no significant difference in nanoleakage was found in MI/MB4 groups between baseline and aged specimens; significant difference in nanoleakage score was observed in MB2 groups. Confocal microscopy analysis showed MB2 Optibond FL and Prime & Bond universal specimens diffusing within the dentine. Contraction gap was significantly reduced in MB2 specimens in both adhesive systems. Degree of conversion (DC) of the MB2 specimens were numerically more compared to MS1 in both adhesive systems.
CONCLUSION: Present study suggests that the new co-blend technique might have a positive effect on bond strengths of etch-and-rinse adhesives to dentine.
